使用者在更新電腦系統中的SPI（Serial Peripheral Interface）ROM晶片中的BIOS時必須承擔一些風險，若不幸於更新BIOS的過程中失敗，就有可能會導致電腦系統無法開機。一般解決的方案通常得送回原SPI ROM晶片廠商進行BIOS修復，該解決方案既費時又沒有效率。而非預期的SPI ROM晶片損壞所造成的電腦系統無法開機，這會讓SPI ROM晶片廠商的維修付出極高的成本代價。然而，業界通常使用雙BIOS（熟稱Dual BIOS）或四顆BIOS（熟稱Quad BIOS）的設計來確保電腦系統正常開機，但需要額外的SPI ROM晶片，而且於主機板上還需要更多數量的針腳（foot print）的設計空間，進而會增加主機板設計的費用成本。The user must bear some risks when updating the BIOS in the SPI (Serial Peripheral Interface) ROM chip in the computer system. If the BIOS fails to update the BIOS, it may cause the computer system to fail to boot. The general solution is usually sent back to the original SPI ROM chip manufacturer for BIOS repair, which is time consuming and inefficient. The computer system caused by the failure of the SPI ROM chip is not expected to be turned on, which will cost SPI ROM chip manufacturers a very high cost.

In this embodiment, the CRC value is a set of CRC check codes obtained by performing data check calculation on all data messages of the main BIOS program 22.

步驟S32，BIOS檢測模組202藉由判斷主BIOS程式22的CRC值是否發生變化來判斷主BIOS程式22是否被損毀。於本實施例中，BIOS檢測模組202將主BIOS程式22的當前CRC值是與原來的CRC值進行比對。若主BIOS程式22的當前CRC值是與原來的CRC值不一致，則說明主BIOS程式22已被損毀，則流程轉向步驟S33；若主BIOS程式22的當前CRC值是與原來的CRC值一致，則說明主BIOS程式22未被損毀，則流程結束。In step S32, the BIOS detection module 202 determines whether the main BIOS program 22 is damaged by determining whether the CRC value of the main BIOS program 22 has changed. In this embodiment, the BIOS detection module 202 compares the current CRC value of the main BIOS program 22 with the original CRC value. If the current CRC value of the main BIOS 22 is inconsistent with the original CRC value, the main BIOS 22 has been corrupted, the flow proceeds to step S33; if the current CRC value of the main BIOS 22 is consistent with the original CRC value, If the main BIOS 22 is not corrupted, the process ends.

步驟S33，BIOS檢測模組202在顯示器4上顯示正在恢復主BIOS程式22的提示訊息。In step S33, the BIOS detection module 202 displays a prompt message on the display 4 that the main BIOS program 22 is being restored.

In this embodiment, the storage device 3 may be an external storage device, such as a USB storage device, or an internal storage device, including a memory, a flash memory, and a hard disk. Wait. If there is a backup BIOS program in the storage 3, step S35 is performed; if there is no backup BIOS program in the storage 3, step S39 is performed.

步驟S35，BIOS恢復模組203檢查所述備份BIOS程式是否有效。若所述備份BIOS程式有效，則執行步驟S35；若所述備份BIOS程式無效，則執行步驟S39。In step S35, the BIOS recovery module 203 checks whether the backup BIOS program is valid. If the backup BIOS program is valid, step S35 is performed; if the backup BIOS program is invalid, step S39 is performed.

步驟S36，BIOS恢復模組203對所述BIOS啟動塊21的防寫保護進行解鎖，並透過已解鎖的BIOS啟動塊21利用所述備份BIOS程式30對已損壞的主BIOS程式22進行恢復。In step S36, the BIOS recovery module 203 unlocks the anti-write protection of the BIOS boot block 21, and restores the damaged main BIOS 22 by the backup BIOS program 30 through the unlocked BIOS boot block 21.

步驟S37，BIOS鎖定模組201重新鎖定SPI ROM晶片2中的BIOS啟動塊21進行防寫保護。In step S37, the BIOS lock module 201 relocks the BIOS boot block 21 in the SPI ROM chip 2 for write protection.

步驟S38，BIOS啟動模組204啟動主BIOS程式22對電腦100進行開機自檢作業（POST），並導入作業系統（OS）完成電腦100的開機啟動過程。In step S38, the BIOS startup module 204 starts the main BIOS program 22 to perform a power-on self-test (POST) on the computer 100, and imports the operating system (OS) to complete the booting process of the computer 100.

步驟S39，BIOS啟動模組204在顯示器4上顯示主BIOS程式22已損壞並無法正常啟動電腦100的錯誤訊息。In step S39, the BIOS startup module 204 displays on the display 4 an error message that the main BIOS 22 is corrupted and the computer 100 cannot be started normally.
